Product Overview
Addressing energy efficiency in sewage pumping systems, the SEV.65.80.22.2.50B provides a solution for grey water and effluent management. This submersible pump is intended for the pumping of contaminated liquids in collection pits where a stable pH between 4 and 10 is maintained. The system is configured for reliable transfer in municipal and commercial pits, supporting wastewater collection and drainage station duties. Its architectural build supports permanent dry or submerged installations where liquid temperatures reach up to 40°C.
Powered by a 2.2 kW motor on a 415v three-phase supply, this model delivers 750 L/Min flow and a maximum head of 18.2 m. The electrical configuration maintains a steady 4.8 Amps rated current at 2895 rpm for consistent torque behavior. This performance profile ensures the evacuation of wastewater through the DN 80 discharge port to protect drainage stations and pump stations. The system is designed for stable operation through a 15-metre Lyniflex power cable that supports integration into wastewater collection systems and infrastructure.
Internal hydraulic behavior is centered on a SuperVortex impeller designed for the passage of solids in suspension. This centrifugal configuration facilitates the free movement of particles up to 65 mm in diameter, preventing the internal clogging that could compromise volumetric efficiency over long-term service. By utilizing a vortex flow path, the unit minimizes internal friction and vibration to extend the life of the rotating assembly. The impeller setup is intended for fluids containing organic materials in municipal and industrial wastewater handling.
Mechanical integrity is reinforced by a cast iron pump body and motor shell with an IP68 rating for permanent dry or submerged installations. Motor protection is anchored by a double mechanical shaft seal in an oil bath featuring a SiC/SiC primary seal and a CER/CARNBR secondary seal. This model includes a DN 80 inlet size for integration into standard wastewater infrastructure and treatment plants. The architectural casting features a stable foundation for reliable operation in subsurface collection pits and drainage stations.
Features
- SuperVortex impeller configuration facilitates the passage of solids up to 65 mm without internal clogging.
- Cast iron housing and motor shell provide a durable foundation for dry and submerged site installations.
- Double mechanical shaft seal in an oil bath with silicon carbide faces ensures protection for the electrical heart.
- Standard 15-metre Lyniflex power cable provides a secure, oil-resistant connection for sewage pumping applications.
- IP68 enclosure rating ensures the motor remains protected during permanent immersion in contaminated wastewater.
- DN 80 inlet and DN 80 outlet connections allow for high-volume effluent transfer through standard pipework.
- Synchronous motor speed of 2895 rpm provides high-velocity discharge for municipal and sewage collection networks.
